You Ask, I Answer: High Quality Design In Vibe Coding

In today's episode, RK asks, how do you get Claude or other coding models to generate such high quality visuals and UI designs during vibe coding? Uh well, here's the first problem in your statement is you say, how do you get high quality designs, but you do not define what that means. If you want great results out of AI, and this has been true since 2023, you have to tell the tools what great results means. What does high quality design mean? Because it's different for everybody.

Think about architecture. Some people, you know, brutalism was a style that was very popular in the 60s and 70s. People loved brutalistic style buildings. Every government building that's been built during that time period, they all look the same. Gigantic blocky buildings, right?

Because that was brutalism. That was the style. That was considered high quality design back then. We might disagree with that now. We might say, well, that's actually just really ugly.

But it's what we agreed on collectively back then. So what does high quality design mean? If you don't have an answer to that, you can't tell AI to generate high-quality design, right? It's like saying generate delicious food. Uh well, okay, cool.

What kind? Right? Do you want sushi? Do you want uh Korean? Do you want Thai?

Do you want uh French food? What does delicious food mean? This is the single biggest issue that most people have when it comes to using generative AI. They do not have clear definitions of what the outcome is in a way that is measurable or clearly defined so that a machine can understand it and generate great results. In vibe coding in particular, there are clear benchmarks for many coding tasks, right?

You have things like cyclomatic complexity, which is a measurement of how many paths are there through a piece of code. Lower is better. And there are deterministic tools that measure, yes, this piece of code has low cyclomatic complexity, or this piece of code has high cyclomatic complexity. Great design, not measurable. You can't say this design is more pleasing on an objective basis that a machine could credibly do with today's tools.

You can absolutely say, how closely does this design mirror or represent or uh appear to adhere to a given standard? So, for example, if you are using um Google's uh material design, which is a popular set of design patterns for UIs and interfaces, you could say, I want to I want this to adhere to the principles of material design, in which case you will get great uh the machines can create that. The machines know what material design looks like. There's an actual specification for material design, and they can adhere to it and generate it. That's what you need.

You need to have something that defines what great design means. If you want it to look like Apple's new liquid glass, which let's be honest, that's just a retreat of Aqua from 20 years ago, um, there's a liquid glass specification. So your first step is to design the specification. Your first step is to talk to your generative AI tool about what great design means to you, and is there an existing specification of some kind that clearly defines an objective, measurable terms, or at least um visible terms that you have you have achieved that style? Think about like architecture, right?

If you were to say, I want a house that looks like a colonial or a Cape Cod or a Victorian style house or an English cottage garden or whatever, uh those all have known design patterns, and those design patterns are things that you can then replicate. There's a great book, oh gosh, now 50 years ago called The Timeless Way of Building by Christopher Alexander that talked a lot about design patterns and how the how we use spaces and we define spaces by how we use them. That philosophy you could literally feed to a language model and say, okay, I like the look of say Walmart's site or IKEA's website or what have you. Based on this, extract out the design principles that this site is using to create a pleasant user experience. What does it do well?

And think about this as a QA exercise now. What does it do well? What does it do poorly? What known design patterns does it use? Um, where could it be better?

What's missing from its design, what's unnecessary in its design? That's your prompt, right? That's your QA, your design QA prompt. And then once you've got once you've defined what good design means to you, maybe you do some deep research projects with it. Then when you're building specs in vibe coding tools, you can say this is the spec to adhere to.

You can say this is what we define as great design. One of the things that people have noted with vibe coding tools is that when they build things like dashboards, they all look the same. Why? Because that's a that's probability at work. If you say make an attractive looking dashboard and you provide no specification, the model is essentially returning an aggregate, an amalgamation of all of the great and not so great dashboard that it has seen online.

It does not have inherent creativity with a poor quality prompter. You have to provide those parameters. When you look at, say, the infographics that AI tools design, unless you specify specific design standard, you all end up with the kind of the same infographic. You can see this with uh tools like Notebook LM. Notebook LM can very clearly, because it's just Gemini under the hood, can very clearly create pretty much any style, but most people don't.

They don't create a they don't prompt it with a specific style for an infographic, and so you end up with exactly the same looking thing all the time. You want an example of this, try this out in Notebook LM. Say, make this infographic, but make it in the style of a Dungeons and Dragons poster, or make it in the style of um a 1960s poster or a 1930s poster, or something that is outside the default, or make sure make it adhere to always having, if you remember my chapter in almost timeless, my book, make sure that there's always a banana in this image somewhere. You have to hide a banana in this image somewhere. You will get at the very least different results and probably better results.

You, if you want to improve AI's design capabilities, you need to have good design language. Because remember, at the core, these things are still large language models. So if you say, I want an infographic in Bento style, right, which is a specific kind of design, you tell it that, it'll do it, and it'll do it really well. If you don't tell it that, it will never know how to do that, and you won't get a good result. So that's my suggestion.

If you want high quality design, you have to define what high quality design means to you. You have to use design vocabulary, uh, and you have to prompt it in such a way that it knows how to create those great designs by your specifications. No spec, no greatness. That's gonna do it for this episode. Thanks for tuning in.
